Impact Lists can undertake the screening process on behalf of the client, whereby it charges a nominal fee for delivering a file that has been washed against the DNCR.
Impact Lists will deliver a washed file with all DNCR records removed. The resultant file of telephone numbers can be contacted as long as the telemarketing calls occur within 30 days of the wash being undertaken.
 
Alternatively Impact Lists can deliver an unwashed file to the client and it is the responsibility of the client to undertake the wash against the DNCR.
